Six months in at 2.4mg. The first four months were close to the trial curve and the last two have been flat, which is roughly what the STEP 1 figure predicts if you read the tail rather than the headline.
Worth knowing that the injection site changes very little. Abdomen, thigh and upper arm are bioequivalent for semaglutide, so a site change is not a plausible explanation for a bad week.
What I am trying to establish is what the dose-response curve actually looks like above 1.7mg, because the trial means hide how few people account for the extra loss.
I have searched first, so if this is covered somewhere point me at it and I will read it.
Short answer first, then the reasoning. The mechanism that matters here is not stomach emptying, it is central. GLP-1 receptor agonism in the arcuate nucleus stimulates POMC neurons and suppresses AgRP/NPY signalling, which is why the effect is appetite and food salience rather than physical fullness. Delayed gastric emptying largely tachyphylaxes over the first months; the appetite effect does not.
Correct me if the detail matters more than I have assumed.

That is correct as far as it goes, and here is where it stops going. Albumin binding above 99% is the whole reason weekly dosing works, and it is also why the trough matters more than the peak. People who dose late are not losing a peak, they are letting the trough fall, and the appetite effect tracks the trough.
If somebody has the primary source to hand I would rather cite it than paraphrase it.

Agreed, though "tolerable" needs defining. A dose you tolerate by eating almost nothing is not tolerated, it is being paid for somewhere else — usually in lean mass, sometimes in adherence three months later.
Clinical perspective, offered as context rather than as advice.
MarkLI_maint said:...but the FDA says semaglutide...
Interesting point. I want to add some regulatory nuance: the FDA labeling reflects the specific clinical trial data submitted for approval. Real-world clinical practice often extends beyond the FDA label based on emerging evidence and clinical judgment.
Example: semaglutide was first approved for diabetes (Ozempic), then obesity (Wegovy). The molecule didn't change — our understanding of its applications expanded. Similarly, semaglutide may evolve as more data accumulates.
